The DPF data format (Dynamic Process Format) was developed by Ucamco (formerly Barco ETS) to represent the individual layers of a printed circuit board. Ucamco also holds the rights to the Gerber format and has further developed it into Gerber X2. Multi-CB still prefers the DPF or Extended Gerber format as Gerber X2 allows misinterpretations.
The DPF data format includes the design of printed circuit board layers (such as conductors, solder pads, vias, etc.) as well as additional information, e.g.
- electrical net list
- embedded aperture definitions
- reverse objects
- contour for outline description
- block apertures to represent Step & Repeat items
